RAILWAY-CAR.

SPECIFICATION forming part of Letters Patent No. 353,884, dated December 7, 1886.

Application filed July 17, 1886. Serial No. 208,307.

To all whom it may concern:

Be it known that we, DENNIS W. RIORDAN and EDWARD J. MARTYN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Railway-Cars, which is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure l is a plan section of a car embodying our invention; Fig. 2, acentral longitudinal vertical sectional view'of the saine, taken on the line x m of Fig. l; Fig. 3, a transverse sectional view taken on the line y y of Fig. 2;

, Fig. 4, a detail sectional view taken on the line a z of Fig. 3, looking in the direction of the arrow, Fig. 5. a detail plan section taken on the line o n of Fig. 3; Fig. 6, a detail view showing the connection between the sills and the uprights; Fig. 7, a detail transverse sectional view showing the construction of the top of the car; Fig. 8, a detail central longitudinal sectional view of the same, and Fig. 9 a detail plan section taken on the line w w of Fig. 8. Figs. 1, 2, and 3 are on the saine scale with respect to each other. Figs. 4, 5, 6, 7, 8, and 9 are on thesauie scale with respect to each other,but on a larger scale than the remaining gures.

Like letter refer to like parts in all the ligures of the drawings.

Our invention relates to railway-cars, and more particularly to the structure or framing of the car-body, and has for its object to produce a car of superior strength and simplicity of construction, and possessing at the same time a higher degree of strength, durability, and much less weight than cars of ordinary construction; and to these ends our invention consists in certain novel features, which we will now proceed to describe, and will then particularly point out in the claims.

In the drawings we have shown our improved construction of a railway-ear as applied to a refrigeratoccar, which is one of its many applications, it being of course understood, however,that the construction is equally applicable to ordinary cars.

We will rst describe the construction of the Hoor or bottom of the car, in which A represents the side sills or solebars. These are (No model.)

constructed of channel-irons U -shaped in crosssection and extending the entire length of the car. The central sill or bolster, B, consists of a timber of suitable dimensions extending the entire length of the car, and having secured to its sides channel-,bars B', as shown more particularly in Fig. 3 of the drawings. The side sills and central sill are connected at suitable intervals by transverse transoms O. These transoms are constructed of I-beams, the ends of which are securely bolted to the channel-bars A, the central portion being depressed to pass underneath the central sill, B, as shown in Fig. 3. The flooring is supported by means of angle-irons D, extending across the car at intervals, and resting upon the channel-bars A and central sill, B, to which they are securely fastened by bolts or rivets. Strips or battens d, of wood, are employed in connection with these angle irons to add to the structural strength, and to receive the nails or other fastening devices which secure the iiooring and outer sheathing.

The flooring or the floor proper, which is attached to the iioorfrainingjnst described,

consists of an outer sheathing, E, of wood,

having on its inner side a layer, e, of paper. An air-space, E, then occurs. Above the angle-irons D and strips d is arranged a layer consisting of an internal layer, El, of hair felt, with a layer of paper, e', below it and alayer of paper, e2, above it, these being secured upon the wooden strips d by means otl transverse battens D and nails d. A layer of paper, e3, and the flooring E3 are laid immediately above these battens D', forming a second space, E4. Of course it will be understood that in an ordinary car not intended for use as a refrigerator-car these protective layers of paper and hair felt will be omitted, the sheathing being applied to the under side of the strips d and the flooring to the upper side thereof.

The sides and top of the car are formed in one continuous structure, the top being in the shape of an arch. The principal elements of the framing of the top and sides are uprights F, consisting of a central strip of wood, f, with flat strips of strap-iron f secured to each side thereof. Each upright has its lower end connected to the side sill, A, as shown in Fig. 6 of the drawings, the said strips f of iron ICO constructed in exactly thc same manner as the Abeing bent around at right angles to the remaining portion at this point, so as to lie flat against the outer surface of the channelbar A, and being secured thereto by bolts or rivets, as shown. Each upright extends upward from the sill to the top of the car, where it is bent into the form of an arch to form the framing of the roof, being then carried down the opposite side and being secured to the sill of that side, the arch and the upright portions all forming one continuous member. Longitudinal braces F connect these members, and diagonal braces F2 are employed -upon the sides to increase the stiness and strength of this frame. rIhe structure which is applied to this framing is identical with that which forms the flooring, and consists of an inner sheathing, G, having a layer of paper, g, applied to its outer side, and the whole being secured to the members F on the inner side thereof. Next comes an air-space, G', followed by a layer of hair felt, G2, with a layer of paper, g', on its inner side and a similar layer of paper, g2, on its outer side. Strips or battens F, parallel to the members F, form an air-space, G3, and to these strips or battens is secured the outer sheathing, G4, provided on its inner side with a layer of paper, g3, and on its outer side, so far as the roof is concerned, with a covering, g4, of tin or sheet-iron.

The roof proper, or arched portion of the continuous structure forming the sides and roof, is additionally strengthened and braced by means of truss-rods H. These truss-rods have their ends secured to the members F at the hip of the arch, each end extending entirely through the said members F, and receiving on its threaded extremity a nut, h, a suitable bloei; or washer, h', being interposed between the member F and the nut, as shown more particularly in Fig. 7 of the drawings. The truss-rod H is V-shaped in its general form, the depressed central angle occurring at the central line of the car. At this point is located a king-bolt, I, the lower forked end of which rests upon the truss-rod H, while its upper threaded end extends up through the member F, passing, of course, through the sheathing. Nuts t" serve to secure the kingbolt to the member F at this point. It will, of course, be understood that one of these truss-rods and king-bolts is employed in connection with each member F, the whole serving to greatly strengthen and stiften this portion ofthe framing..

An angle-iron, J, is riveted by means of rivetsj to the members F and sheathing G along the inner side of the car, near the top thereof, at the springing of the arched roof. This angle-iron extends along the entire length of both sides of the car, and also across the ends thereof, and serves not only to strengthen and sti ffen the structure, but also to form the point of attachment of the bars upon which the meat or other article to be transported is hung in refrigeratorcars. The ends of the car are sides, and therefore need no detailed description here.

By reason of the constructionwhich we have just described we are enabled to produce a car which possesses in a high degree both strength and lightness. The structure possesses many obvious advantages, which it is `unnecessary to detail here, the principal one being, however, the construction of the sides of the roof in one continuous structure, thus adding greatly to the strength and simplicity of the car-body.

It is obvious that various modifications in the details of the construction we have just described may be made Without departing from the`limits of our invention. For instance, although we have described our invention as applied to a refrigerator-car, it is obvious that the various layers of hair felt and paper may be dispensed with and the outer and inner sheathings applied directly to the` outer and inner sides of the members which form the framing. Moreover, various other modifications in unimportant features will readily suggest themselves, and we therefore do not wish to be understood as limiting ourselves strictly to the precise details hereinbefore described and shown in the drawings.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
